Research Findings: This study examined the contribution of several classroom experience measures (classroom characteristics, teacher characteristics, and teacher-child interactions) to preschoolers' improvement in visuomotor integration. Children (N = 467) ranged in age from 3 to 5 years old and were enrolled in 115 classrooms in 5 U.S. states.…

Prior research has established the potential for achievement gains from attending smaller classes. However, large statewide class-size reduction (CSR) policies have not been found to consistently realize such gains. A leading explanation for the disappointing performance of CSR policies is that schools are forced to hire additional teachers of…

This paper investigates the effects of California's billion-dollar class-size-reduction program on student achievement. It uses year-to-year differences in class size generated by variation in enrollment and the state's class-size-reduction program to identify both the direct effects of smaller classes and related changes in teacher quality.…

According to Tennessee's 4-year study of class size, smaller classes (13 to 17 students) have an advantage over larger classes in reading and mathematics in the early primary grades. Another study showed that fourth graders previously enrolled in Project STAR classes out-performed non-STAR students. Benefits are greater when teachers possess…

This is a report of a study designed to discover the nature of interactions between teachers and students in regular-size classes (25 or more students) and small-size classes (fewer than 18 students). It also describes the efforts of one public school to maintain smaller classes. A review of the literature and observations of 11 primary classrooms…

The impact of class size reduction at the early levels on student achievement in various states is discussed in this report. The Tennessee Student Teacher Achievement Ratio (STAR) study, a statewide longitudinal evaluation of the effects of class size on student achievement and development in primary grades K-3, analyzed demographic and basic…

This research brief summarizes a report by Christopher Jepsen and Steven Rivkin, "Class Size Reduction, Teacher Quality, and Academic Achievement in California Public Elementary Schools" (2002) [ED497298]. Intuitively, class size reduction is a good idea. Parents support it because it means that their children will receive more…

Intuitively, class size reduction is a good idea. Parents support it because it means that their children will receive more individual attention from teachers. Teachers like it for the same reason and also because it creates a more manageable workload. It is generally assumed that the fewer students in a class, the better they will learn and the…
